In a digital world where website speed and performance directly affect user experience, Google introduced Core Web Vitals, which includes three key metrics to measure website performance. But why are these indicators so important?

Introducing Core Web Vitals

Core Web Vitals consists of three main metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics are direct user experience metrics that show how fast a page loads, how quickly it responds to user interactions, and how stable the page structure is during loading.

Why are Core Web Vitals important to Google?

THE Google has always placed great emphasis on user experience. This year, as mentioned by forbes.com, companies should work with expert web developers, performance optimization experts or web development agencies to improve their websites' LCP performance and user experience.

In addition, according to a searchenginejournal.com article, the most popular content management systems in 2023, such as WordPress, Wix and Shopify also showed significant improvement in Core Web Vitals metrics. This shows that website performance optimization is not just a trend, but an expectation in today's digital world.

The Core Web Vitals indicators not only affect the ranking of websites, but also directly affect the user experience. In order for your website to be successful in 2023, it is essential that you pay attention to these indicators and optimize your site for the best results. But don't worry, this article will show you step by step how you can do it!

Introducing Core Web Vitals metrics

To measure website performance, Google has introduced three key metrics that directly target user experience. These metrics are Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). But let's take a closer look at what these terms mean!

Largest Contentful Paint (LCP): What is it and why is it important?

LCP measures how long it takes for the largest content element on a page, such as an image or a block of text, to load. This indicator directly affects the user experience, as people do not like to wait a long time for a page to load. According to an HTTP Archive report, in 2023, the most popular content management systems, such as WordPress, showed a significant improvement in this area.

How can we measure LCP?

LCP can be measured using several tools, such as Google PageSpeed Insights or Chrome DevTools. These tools provide detailed information about page load times and which elements slow down LCP.

Tips for improving LCP

• Optimize images: Use image compression tools and modern image formats like WebP.
• Use fast hosting: Server response time directly affects LCP.
• Minimize third-party codes: Some plugins or scripts can slow down your site.

First Input Delay (FID): What is it and why is it important?

FID measures how much time elapses between the first interaction (such as clicking a button) and the browser's response. A high FID value means that the site is not responding quickly to user interactions, which can be frustrating for visitors.

How can we measure FID?

FID can be measured using the Chrome User Experience Report or Google PageSpeed Insights.

Tips for improving FID

• Minimize or delay running JavaScript: Too much JavaScript can slow down the page.
• Use browser storage: This helps the page load faster on repeated visits.

Cumulative Layout Shift (CLS): What is it and why is it important?

CLS measures how stable the structure of a page is during loading. If items move while loading, it can be confusing for users and increase bounce rates.

How can we measure CLS?

CLS can be measured using Google PageSpeed Insights or Chrome DevTools.

Tips for improving CLS

• Specify a fixed size for media content: For example, images and videos.
• Minimize or avoid animations and dynamic content that can move page elements.

Understanding and optimizing these metrics is essential to providing a great user experience and improving Google rankings. In the following sections, we will give you more tips and tricks to improve the performance of your website!

How do Core Web Vitals affect rankings?

Website performance and user experience have always been key factors for Google. In recent years, Google has made several changes to its ranking algorithm to better reflect the real user experience. The introduction of Core Web Vitals indicators was one of the most important steps of these changes.

Changes to Google's ranking algorithm

Among the latest changes to Google's ranking algorithm is the introduction of Core Web Vitals metrics. According to an HTTP Archive report, in 2023, the most popular content management systems, such as WordPress, showed a significant improvement in these indicators. This shows that website performance optimization is not just a trend, but an expectation in today's digital world.

The role of user experience in ranking

Google has always focused on user experience. With the introduction of Core Web Vitals metrics, the company has made it clear that website performance has a direct impact on rankings. User experience is not only about how fast a page loads, but also about how stable and reactive the page is. According to the searchenginejournal.com article, the most popular content management systems, such as WordPress, Wix and Shopify, also showed significant improvement in Core Web Vitals indicators.

The Core Web Vitals indicators not only affect the ranking of websites, but also directly affect the user experience. Websites must be excellent not only in terms of content, but also technically in order to rank high in the eyes of Google.

Unoptimized images and media files

Large and unoptimized images can significantly slow down page load times.

Solutions:

• Image compression: Use tools like TinyPNG or ImageOptim to reduce the size of images without losing quality.
• Modern Image Formats: Switch to WebP or AVIF instead of traditional JPEG and PNG.
• Lazy loading: Use the "lazy loading" technique to delay the loading of images and videos until the user scrolls there.

Inefficient JavaScript and CSS

Redundant or poorly optimized code can slow down the site and degrade the user experience.

Solutions:

• Code minification: Use tools to minify JS and CSS files, such as UglifyJS or CSSNano.
• Deferring code: Defer the loading of non-essential JavaScripts using the "async" or "defer" attributes.
• CSS Critical Path Optimization: Use tools to extract and embed critical CSS in HTML headers.

Layout changes and animations

Unexpected layout changes and excessive animations can be confusing for users and increase the value of Cumulative Layout Shift (CLS).

Solutions:

• Set fixed sizes: Set fixed sizes for images, videos and other media elements to avoid unexpected page layout changes.
• Limit animations: Avoid excessive and unnecessary animations, especially those that move the content of the page.
• Use CSS transitions: Use CSS transitions for animations, as they are often more efficient and less confusing for users.
